Abstract
We developed systematic and basic rules of reaction dynamics of three model compounds, 2-MethylFuran, N-MethylMaleimide, and anthracene across the range of temperatures and UV light to establish the selective rule of the Diels-Alder (DA) reaction and photodimerization among them. Analysis of results was investigated through H-NMR using d-chloroform as solvent. Due to its efficient thermal stability, those three compounds were selected in this work. This study suggests a basic reference to improve the control of crosslinking reactions among them which can further induce the change of polymer properties. Through this work, it was shown that both DA reactions of furan-maleimide and anthracene-maleimide were carried out at low temperatures (30°C, 40°C, and 50°C) at a similar rate. On the other hand, at 120°C retro-Diels Alder reaction only between furan and maleimide occurred. Furan and maleimide bonds were broken; while anthracene was linked with maleimide even more than it was at the low temperatures. Photodimerization of anthracene under UV light (λ=365nm) showed very low concentration (~6%). This was because of the low solubility of the solvent we used. Therefore it was difficult to obtain the high concentration of anthracene dimers on H-NMR analysis. These findings can further influence the polymerscale research among these compounds to accomplish the versatile responsive polymer chemistry.
